Depression: Telling It Apart From Ordinary Sadness
Depression is a medical condition in which low mood, or a loss of interest and pleasure in things that used to matter, persists for at least two weeks, is present most of the day on most days, and is accompanied by changes in sleep, appetite, energy, concentration and self-worth. It is not the same as sadness, which is a healthy response to loss and which lifts when circumstances or company change. It is also not weakness, laziness or a deficiency of faith, and treating it as a character problem is the reason so many people arrive years late. In Pakistan it very often presents physically — persistent body aches, exhaustion, poor appetite, weight loss, headaches — rather than as a stated complaint of sadness. It is treatable, and most people recover: mild depression usually responds to structured self-help, a return to activity and exercise, while moderate and severe depression respond to talking therapy, to antidepressant medicines, or to both together. Antidepressants take two to four weeks to begin working and are continued for months after recovery to prevent relapse. The most important thing to know is what to do about thoughts of suicide, which are a common symptom of the illness rather than a character flaw: tell someone immediately, do not stay alone, remove access to medicines, pesticides and weapons, and go to the nearest emergency department or call Rescue 1122 the same day.

What depression is, and what it is not
Grief after a death, low spirits after losing a job, a flat few weeks after an illness — these are healthy responses, and treating them as a disease does nobody any favours. Ordinary sadness fluctuates. It lifts in good company, it allows enjoyment of something for an hour, and it is tied to a cause a person can name.
Depression is different in ways that can be described precisely. Low mood or the loss of interest and pleasure — the technical word is anhedonia, and it simply means nothing feels enjoyable any more — is present most of the day on most days, for two weeks or longer. Alongside it come changes in the body's machinery: sleep, usually broken with waking in the early hours and being unable to return to sleep; appetite and weight; energy that does not return with rest; thinking and concentration that slow to the point where a familiar task becomes hard. Self-worth collapses, guilt becomes disproportionate, and the future looks fixed rather than uncertain. In roughly a third to a half of people, thoughts of death or of ending life appear.
The hopelessness is itself a symptom, and this is the part worth holding onto: depression tells the person experiencing it that nothing will help and that they are a burden. That is the illness talking, and it lifts with treatment along with everything else.

How it shows up here
Many people in Pakistan reach a doctor with a body rather than a mood: pain in the limbs and back, heaviness in the head, burning in the hands and feet, gas and poor appetite, a year of tiredness. Others describe dil bhaari hona or say simply that there is tension. None of this is a lesser form of depression, and none of it means the physical symptoms are fictional — they are how the illness is experienced and expressed. It does mean that a person can spend two years and a good deal of money on tests before anyone asks about sleep, appetite and interest.
The other reason for delay is that depression is widely understood here as a moral or spiritual matter — insufficient faith, ingratitude, weak character, or the effect of nazar or jadoo. It is not the job of a medical page to argue with anyone's beliefs, and prayer, community and family genuinely help a great many people through illness. What can be said plainly is this: depression occurs in the devout and the sceptical alike, it responds to treatment in both, and seeking that treatment is no more an admission of weak faith than taking treatment for would be. Nobody should be charged money to stop a prescribed medicine.
What causes it
There is rarely a single cause. Depression arises from a combination of vulnerability and circumstance: genetics and temperament, adverse experience in childhood, the events of the present, and physical health. Long-term illness is a large contributor — depression is roughly twice as common in people with , heart disease or pain, and the relationship runs both ways, because depression also makes those conditions harder to manage.
- Life circumstances: bereavement, separation, financial hardship, unemployment, insecure housing, caring for a dependent relative, and violence or coercion at home.
- Physical illness: any long-term condition, chronic pain, , and the months after a serious illness or surgery.
- Hormonal and metabolic causes: , which is common and easily missed; the weeks after childbirth; and the menopause transition in some women.
- Nutritional: , which is very common here and produces overlapping symptoms, and severe deficiency, which is also common — though correcting it is not itself a treatment for depression.
- Substances: alcohol, cannabis and stimulants, all of which lower mood over time whatever they do in the moment.
- Medicines: , isotretinoin, some hormonal treatments and a few others. If low mood began within weeks of a new medicine, tell the prescriber rather than stopping it yourself.
- Sleep: sustained sleep deprivation both triggers and worsens depression, and shift work makes it harder to treat.
How it is assessed
By listening, mostly. A doctor asks about mood, interest, sleep, appetite, energy, concentration and self-worth over the past two weeks, about alcohol and drugs, about what has been happening, and directly about thoughts of self-harm. The PHQ-9 questionnaire is often used to measure severity and to track whether treatment is working; like the GAD-7 used for anxiety, it measures rather than diagnoses, and a score is not a label.
A small set of blood tests is usually done once, to catch the physical conditions that imitate depression: for the , a for , blood sugar or , and often a level. Normal results do not mean the depression is imaginary; they mean the treatment can now be aimed at the right target.
How it is treated
Treatment is matched to severity. For mild depression, the first steps are structured activity, exercise, sleep repair, reconnecting with people, and guided self-help — and these are genuine treatments with evidence behind them, not a way of putting someone off. Behavioural activation is the most useful single idea: motivation returns after activity rather than before it, so the plan is to do a small, specific, scheduled thing whether or not you feel like it, and let the feeling follow.
For moderate and severe depression, talking therapy, medicine or both are used. Cognitive behavioural therapy and interpersonal therapy both have strong evidence. Antidepressants, most often from the SSRI group to begin with, are effective for moderate and severe illness; the evidence that they add much to self-help in very mild depression is weak, which is why they are not usually the first move there.
Four things about antidepressants are worth knowing before starting, because not knowing them is the usual reason a course fails. They take two to four weeks to begin helping and six to eight weeks for the full effect, so week two is not the time to judge. — nausea, headache, restlessness, sleep changes, effects on sex — are commonest at the start and usually settle. They are continued for at least six months after you feel well, because stopping as soon as the mood lifts is the commonest cause of relapse. And they are stopped by gradual reduction, never abruptly. In people under 25, thoughts of self-harm can increase in the first weeks, which is why early and close follow-up is arranged rather than why the medicine is avoided. Choice, dose and duration are the prescriber's decisions.
Some things are widely sold and do not treat depression: multivitamin drips and injections, unregulated herbal tonics, and sedative tablets such as alprazolam, which may make sleep easier for a week while doing nothing for the illness and adding a dependence problem to it. Alcohol reliably makes depression worse. If someone offers a guaranteed cure, they are describing something no treatment in psychiatry can honestly claim.
What you can do yourself
- Act before you feel like acting. Pick one small scheduled thing a day — a twenty-minute walk, one household task, one phone call — and do it regardless of mood. This is the core of behavioural activation and it is the most useful self-help in depression.
- Walk most days. Exercise has a real, measurable antidepressant effect. Thirty minutes of brisk walking, or three shorter walks, is enough to count.
- Fix the waking time first. Get up at the same hour every day even after a bad night, get daylight early, and avoid daytime sleep. Sleep repairs from the morning end.
- Tell one person. Not everyone — one person who will check on you. Isolation is both a symptom and an accelerant.
- Eat something regularly even without appetite, and keep drinking water. Weight loss and dehydration make concentration and energy worse.
- Stop alcohol and cannabis. Both lower mood over days and both interfere with treatment.
- Attend to physical health, because it feeds back into mood. Our guide to eating on a Pakistani plate is a reasonable place to start.
- Postpone big decisions — resigning, separating, selling something — until you are better. Depression distorts judgement about the future, and decisions made inside it are often regretted outside it.
- Write down what you will do if things get worse, including who you will call and which hospital you will go to. A plan made on a good day is worth a great deal on a bad one.
How to help someone else
- Listen without fixing. Being heard is worth more than advice, and advice offered too early sounds like dismissal.
- Ask directly about suicide. Use plain words. It does not plant the idea, and it may be the first time anyone has made it possible to answer.
- Do not say that others have it worse, that it is a matter of faith, or that they should be grateful. Every one of those lands as blame.
- Offer specific practical help — a lift to the appointment, sitting with them while they call, taking the children for an afternoon. Open offers are rarely taken up.
- Keep in touch after the crisis passes. The weeks after an episode are when people are most alone and, for someone who has recently self-harmed, remain a period of real risk.
- Look after yourself too. Supporting someone through depression is genuinely tiring, and you are allowed to ask for help with it.
Living with it, and what recovery looks like
Most people with a first episode of depression recover, many completely. About half will have another episode at some point in their lives, and the risk falls with each of these: completing treatment rather than stopping early, staying on medicine for the full period after recovery, and learning the personal early warning signs — usually sleep going first, then withdrawal, then loss of interest. Recognising those and acting within a fortnight often prevents a full episode. Recovery is generally gradual and uneven: sleep and energy improve before mood, and the ability to enjoy things is usually the last thing to return. A flat week during recovery is not a relapse.
When to see a doctor
Go to hospital today, or call Rescue 1122, if you are thinking of ending your life, if you have harmed yourself, if someone has taken an overdose, or if a person has stopped eating and drinking or cannot care for themselves or their baby. Book an appointment if low mood or loss of interest has lasted more than two weeks, if sleep, appetite, energy or concentration have changed and stayed changed, if unexplained physical symptoms have been investigated and nothing has been found, if you are drinking more to cope, if you have had depression before and recognise it starting again, or if you are a new mother struggling in the weeks after delivery. Bring a list of your medicines, and say honestly how much alcohol or how many tablets you are taking; treatment cannot be got right around a gap in the history.
